Does this answer your question? [Cannot find module 'rxjs-compat/Observable'](https://stackoverflow.com/questions/52388927/cannot-find-module-rxjs-compat-observable) — Harun Yilmaz, Oct 05 '20 at 08:52
yes I tried but not working . is this issue related to version?? — RANA 04, Oct 05 '20 at 11:05
`rxjs-compat` is used as a workaround for migration from v5 to newer. I think you should consider refactoring your code to use `rxjs` instead of `rxjs-compat`. This [article](https://medium.com/@cartant/rxjs-avoiding-rxjs-compat-4b79a566359b) might help — Harun Yilmaz, Oct 05 '20 at 11:52

It is due to mismatching of the version you downloaded and the angular version. You have to choose whether it is suitable or not to the angular version you use..

You need to import classes from rxjs like so:

import { Observable, Subject } from "rxjs";

Why? rxjs changed their export layout to use a single export file instead of using paths to specify dependency locations.
